Glera is a white grape variety primarily grown in the Veneto region of Italy. It is best known for being the main grape used in producing Prosecco, a popular sparkling wine. Glera grapes thrive in the region's climate, which features warm days and cool nights, allowing for balanced acidity and fruity flavors. The Glera grape has a light, fresh taste with notes of green apple, pear, and floral aromas. It is typically harvested early to maintain its acidity, which is essential for creating the crisp and refreshing profile of Prosecco. Glera is also used in some still wines, showcasing its versatility.
